WASHINGTON — Green groups are split over whether President Joe Biden should step aside for another Democrat in the US election, with some concerned his weakening polling against fossil fuel booster Donald Trump could hamper turnout and jeopardise his climate wins.

Biden, 81, is under pressure and scrutiny from some lawmakers, donors and activists to drop his reelection campaign in the wake of a disastrous presidential debate performance this month that renewed questions about his mental fitness.

Environmental groups are anxious at a potential second Trump administration, after his 2017-2021 term brought sweeping roll-backs of environmental regulation and restrictions on oil drilling, plus withdrawal from an international pact.

A second Trump presidency would almost certainly seek to erase many of Biden's climate policy wins, including rolling back major vehicle and power plant rules and repealing or weakening key parts of the current administration's signature climate law the Inflation Reduction Act, according to his campaign speeches and policy agenda.
